Chapter 11 – Data Commands
Using AT Commands During a Data Connection
To use AT Commands during a data connection (such as while the product is in online mode), it is necessary either to
switch to offline mode, or to use the +WMUX command to enable Commands / Data multiplexing.
Switch from Online to Offline Mode
To switch from online mode to offline mode, the “+++” sequence must be sent. Following this, the product gets back
to offline mode with an “OK” response, and an AT command can be sent.
Note: The “+++” sequence only works with the +ICF command using the following settings:
• 8 data bits, with no parity
• 7 data bits, with even parity
Switch from Offline to Online Mode
See the ATO command description.
